全球变化背景下，土壤有机碳的来源和累积途径是碳固持与稳定机制研究的重点内容。植物和微生物的生物分子是土壤有机碳累积的重要来源，为了对植物和微生物驱动的土壤有机碳累积有更全面的认识，本文结合已发表文献深入剖析了土壤中植物源碳和微生物源碳累积的研究进展。结果表明:1)微生物残体是近年来研究的前沿内容;相较于森林生态系统，草地和农田生态系统的微生物残体碳研究是当前的热点。2)土壤有机碳累积的分析方法更加多样化和精细化，但植物源碳和微生物源碳的定量方法还不完善。3)增温或模拟氮沉降对植物源碳和微生物源碳累积的影响是研究的热点内容，但不同研究的结论并不一致，具体机制尚不明确。建议未来进一步加强不同来源有机碳的精确定量，深入分析不同来源有机碳累积的影响机制，同时完善降水变化、二氧化碳浓度升高、土地利用变化等全球变化因子及其交互作用对不同来源土壤有机碳累积的影响研究。
Research Progress on Plant-and Microbial-Driven Soil Organic Carbon Accumulation:A Bibliometric Analysis
The sources and accumulation pathways of soil organic carbon(SOC)constitute fundamen-tal aspects of carbon sequestration and stabilization research amidst global change.Plant and microbial bio-molecules play a pivotal role in SOC accumulation.To gain a deeper understanding of how plant and micro-bial biomolecules drive SOC accumulation,this paper collates published research to offer an extensive analysis of progress made in the field of plant-derived and microbial-derived carbon accumulation in soils.The findings reveal:1)Microbial residues have emerged as a leading area of research in recent years,with studies on microbial necromass carbon in grassland and agricultural ecosystems outnumbering those in for-est ecosystems;2)While methods used to investigate SOC accumulation have become more diverse and sophisticated,there are still limitations in quantifying plant-and microbial-derived carbon;3)The impact of warming or nitrogen addition on the accumulation of plant-and microbial-derived carbon has been exten-sively explored,yet results are inconsistent,and the underlying mechanisms remain elusive.Future research should leverage advanced techniques to enhance the precision of quantifying various SOC sources and delve into the inherent mechanisms of SOC accumulation across diverse scenarios within the context of global change.Additionally,there is a need to broaden the scope of studies to include other global change factors such as precipitation changes,elevated carbon dioxide concentrations,land use alterations,and their interactive effects on SOC accumulation from diverse sources.
